Flow characterization of a flotation column

The Canadian Journal of Chemical Engineering, 1989
Abstract The flow characteristics of a froth flotation column have been experimentally studied using air and aqueous surfactant solutions without the presence of solids. The hold‐up behaviours of the bubbly and the froth zones of the column were linked together using the drift‐flux model.

Semi-batch flotation column

Minerals Engineering, 2012
Abstract A compact (75 cm ht × 7 cm dia.) semi-batch type flotation column was developed for use as a convenient testing and research apparatus especially in laboratories that do not have sufficient headroom for a full-size experimental column installation.

Automatic Control of Flotation Columns

2010
Since their first commercial application for mineral separation in the early 1980s, flotation columns have become a standard piece of equipment in mineral concentrators particularly for cleaning operations. This chapter presents and discusses the most recent advances in instrumentation and automatic control of flotation columns.

Developments in the control of flotation columns

International Journal of Mineral Processing, 1988
Abstract The methods used currently for the control of flotation columns are summarised. The major deficiency of these methods is that they rely on inaccurate and indirect measurements of slurry-froth interface level and bias flowrate (the net downward flowrate of water through the froth phase).

Troubleshooting industrial flotation columns

Minerals Engineering, 1995
Abstract Since the early 1980s flotation columns have been progressively incorporated in milling operations all over the world. Improvements in final concentrate grade, using single cleaning stages, have been in most cases the reason for using this new technology.

Comparison of Flotation Column and Mechanical Cell in Coal Flotation

2004
Flotation is universal method to fine coal processing. Selectivity and efficiency of flotation depends not only on surface characteristics of particles, but also on hydrodynamic condition in flotation cell. The goal of the research was to compare flotation column and conventional mechanical flotation cell in coal flotation. The tests was carried out in
